Claims

[Scope of utility model registration request]

An annular disk having an outer diameter smaller than the outer diameter of the rotor is inserted into an annular groove carved in either the rear case, the front case, or the front case, and the annular disk is pressed against the opposing end face of the rotor to form a rotor catch case. Or a rotary compressor characterized by reducing the clearance between the front cases.
